RAIL-JOINT.

Specification of Letters Patent.

Patented Apr. 8, 1919.

Application filed November 21, 1918. Serial No. 263,575.

To all whom it may concern:

Be it known that I, SAMUEL A. BOYD, a citizen of the United States,residing at Sasakwa, in the county of Seminole and State of Oklahoma,have invented certain new and useful Improvements in Rail-Joints, ofwhich the following is a specification.

This invention relates to rail joints and has for its object to providea comparatively simple and thoroughly eflicient device of thischaracter, by means of which the confronting ends of rails in a line oftrack may be quickly and conveniently coupled and said rails securelyheld in longitudinal alinement under all conditions of service.

A further object of the invention is to provide a safety joint, the railends of which are provided with interlocking parts disposed beneath therails and so constructed as to prevent sagging of the abutting endsthereof, thereby obviating the necessity of tamping up low joints andeffectually preventing pounding and mutilation of the rail ends incidentto the travel of cars and other rolling stock thereover.

The invention further aims to provide a rail joint, the rail ends ofwhich are interchangeable so that when one side of any rail becomes wornor otherwise impaired from constant use the position of said rail may bereversed whereby to present a fresh track surface to the car wheels.

The invention further contemplates a joint which may be applied to thestandard type of rail without necessitating any structural changestherein and in which wear and strains on the angle bars and securingbolts are reduced to a minimum.

A still further object is generally to improve this class of devices soas to increase their utility, durability and eliicienc Figure 1 is aperspective view 0 a portion of a railroad track provided with a railjoint constructed in accordance with the present invention;

Fig. 2 is a. detail side elevation of one of the joints;

Fig. 3 is a bottom plan view;

Fig. 4 is a detail perspective view of abutting ends of mating sectionsshowing the construction of the locking device;

Fig. 5 is a detail transverse sectional view.

The im roved joint forming the subjectmatter 0 the present invention isprincipally desi ed for connecting the con fronting en a of railwayrails and' by way.

of illustration is shown applied to a section of track in which 5designates the rails, 6

the abutting ends thereof and 7 the crossties to which the rails aresecured.

Secured to or formed integral with the base flanges 8 of the rails atthe abutting ends thereof are depending enlargements indicated as awhole at 9, said enlargements being provided with interlocking parts,the construction of which will be more fully explained hereinafter. Theenlargements 9 register with each other when the rails are assembled andserve to reinforce and brace the rails at the abutting ends thereof soas to effectually prevent sagging of the rail ends and pounding ormutilation of said ends incident to the passage of cars and otherrolling stock thereover. When the rails are assembled, the extensions 9fit between and bear against the'adjacent crossties 7 and in whichposition they are se- I -urely held by means of spikes or otherfastening devices 10 driven into the crossties and engaging suitableangle bars or fish plates 11, as shown. are provided with elongatedopenings 12 for the passage of securing bolts 13 which latter extendthrough the webs of the rails in the usual manner so as to permitexpansion and contraction of the rails due to temperature changes.

The rear end of the enlargement 9 of each rail preferably extends theentire width of the base flange thereof and is cut away to form ahorizontally disposed lip 14 also preferably extending the entire widthof the base flange of the rail, as shown. Spaced from the lip 14 is asubstantially L-shaped extension 15, the long arm of which is preferablysubstantially one-half the width of the base flange of the rail, whilethe short arm of the extension extends substantially the entire width ofthe base flange of the rail andhas its under side cut away to form atransverse locking lip 16 adapted to fit within the groove formed by thelocking lip 14 of a'mating rail end when the rails are assembled. Theextension 15 is spaced from the adjacent lip 14 to produce anintermediate passage 17 which accommodates the short arm 18 of theadjacent L-shaped extension so that when the rails are assembled theinner'faces of the extensions 15 will abut and thus prevent lateraldisplacement of the rail ends. It will here he noted that the extensions15 project longitudinally beyond The angle bars 11 the abutting ends 6of the rails so that when the rails are assembled the extension 15 ofone rail will overlap the base flange'of the adjacent rail. and thusform a firm anchorage and reinforcement for the abutting ends of saidrails. The recesses 17 open through the opposite longitudinal edges ofthe rails so that the rails may be readily-assembled by causing the li s16 to register with the re- 10 cesses formed y the lips 14 and thenpressing laterally on the rail ends until the adjacent faces of theextensions 15 abut and 1n which position the rails will be securely heldin longitudinal alinement. It will, of 15 course, be understood thatthere will be sufficient play between the extensions and the lips 14 toallow for expansion and contraction of the rails under temperaturechanges. The locking members are identical in con struction with theexception that the extension 15 at one end'of each rail is arranged onone side of the longitudinal axis of the rail, whereas the extension onthe opposite end of the rail is disposed on the other'side of the otherlongitudinal axis of the rail. By making the locking members in thismanner the railends are rendered interchangeable so that should thetread surface of a rail bei come worn or otherwise impaired fromconstant use the position of the rail may be readily reversed thereby topresent a new tread surface to the car wheels. It will, furthermore, benoted that the locking members comprisingmy improved joint are disposedentirely beneath the base flanges of the rails so as to render itunnecessary to out or otherwise weaken the vertical webs or tread facesof the rails and permitting the device toxbe used in connection with thestandard 40 type of rail Without necessitating any structural changestherein, it being merely necessary to weld or otherwise secure theinterlookin parts on the base flanges of the rails as wil be readilyunderstood. Moreover, as

the interlocking members comprising my improved joint are disposedbeneath the rails at the abutting ends thereof, strain and wear on thebolts and angle bars is reduced to a minimum.

A joint constructed in accordance with the present invention may bequickly coupled, and effectually prevents sagging or low joints at theabutting ends of the rails with consequent ounding and damage to both.the

rail endsand Wheels'of the rollingstock.
